ronT'BLE runt-BURNER CONSTRUCTION Application lei October 5, `1927. Serial No. 224,133.

My invention relates to improvements in fuel burner construction wherein 'a plurality of burner units are detachably mounted and made separately removable from a fabricated portable mounting box.

The primary object of my invention is to provide an improved construction and arrangement for fuel burners.

Another object is to provide animproved 1o construction wherein vertically disposed burner tubes are arranged in burner units arranged to be inde endently mounted and separately removed rom a mounting.

' A further object is to provide an improved burner construction comprising a plurality of separate burner units each consisting of an integral structure, forming fuel manifold,

vburner tube and nozzle mounting, induction tube supports, and unit sup orts, to facilitate construction and assem ly and permit the ready removalof any particular unit inl dependently of the remaining units.

Another object is to provide an improved burner for vertical ring whereby separate units may be independently removed without shutting down the remaining burners and without interrupting the operation of the burner.

A further object is to provide an improved 3o means for mounting burner units within a mounting box to facilitate the placing and removing of burner units. v

A still further object is to provide an improved burner construction which is entirely self-contained and which is readily transportable.

I accomplish these and other objects by means of the improved device disclosed in the drawings forming a part of the present application wherein like characters of reference are used to designate similar parts 4throughout the specification and drawings and in which,

Fig. 1 is a broken plan-view ofmyimproved burner construction;

Fig. 2 is a longitudinal vertical section of .the burner; p

Fig. 3 is' a front elevation of the burner construction, partly broken away and shown 50 in transverse section;

Fig. 4 is a broken side elevation of one of my improved burner'units showing the manner in which said unit is detachably mounted;` and Fig. 5 is a front elevation of the burner 55 unit and unit mountingmeans.

Referring to the drawings, the numeral 1 is used to designate in general .a mounting box consisting of a frame fabricated from structural angle iron, to form corner posts 2 60 vconnected at their tops by upper beams 3 extending vacross the sides, and beams 4 extending across the front and back of the box. The posts 2 and the beams 3 and 4 are for'med from' angle iron sections arranged in abut- 65 ting relation as shown in the drawings. Bottom angle iron sections 6 and 7 are connected between the bottoms of the posts 2 across the Sides and across the front and-back respectively.

A bottom plate 8.l formed from suitable sheet metal. issecured across the bottom of the frame,v and plates 9 are secured upon the Sides of the frame. A damper frame 11 is hingedly mounted within *the front of the frame 1 and upon said frame 11 is pivotally mounted a damper plate 12 supported upon a damper shaft'13 engaged by notches 14 formed in outwardly extending flanges 16.

`The damper plate extends substantially so across the frontof the box and is tiltable upon the shaft 13 Ato provide` a desired degree of opening to' admit air to the burner box. The back of the box 1 is'provided with an upper door portion .17 hingedly connected to S5` the top portion of the box frame, and a lower 'door portion 18hingedly connected to the lower angle member 7 'Ihe door portions 17 and 18 have their adjacent edges arranged to meet in substantially abutting relation, and Inatchf' ing recesses 19 are formed in said'edges for a purpose hereinafter more fully explained.

A plurality of burner units are detachabl mounted within the mounting box 1, eac unit consisting of a fuel manifold 21 having 95 a plurality of induction tube supports 22 formed integrally therewith and supported above the manifold by webs 23 cast integrally with the manifold and supports. The supports 22 are provided with upwardly disloo v posed annular seats arranged to receive the lower edges of induction tubes 24 formed` from suitable refractory material such as in common usage. Burner tubes 26 are connected into the manifold 21 in axial alinement with the tube supports 22, said burner tubes 26 extending upwardly through the supports 22 and into the induction tubes 24. Nozzles 27 are mounted upon 'the upper ends of the burner tubes 26 through which fuel is delivered upwardly for combustion. A sup orting arm 28 is formed upon one end o the manifold 21. The opposite end of the manifold 21 is connected to a fuel supplyconnection 29, arranged to extend outwardly through the back of the box 1 through the matching recesses formed in the edges of the doors 17 and 18.

The burner units are removably supported within the box 1 by means of brackets secured Within the front and back of the box 1, each bracket consisting of a pair of arms 31 secured at their upper ends upon the beams 4 and extending downwardly in spaced parallel relation. Each pair of bracket arms 31 at the front of the box 1 is arranged to receive the end of a supporting arm 28 of a burner unit, and the corresponding pair of bracket arms 31 at the back of the box is arranged to receive the supply connection 29 of the unit, said unit being moved upwardly into engagement with the spaced ends'of the arms 31. Retaining pins 32 are arranged to be inserted into engagement with notches 33 yformed in the tops of laterally extending lugs 34 formed upon the bottoms of the arms 31, said pins spanning the space between the arms and sup porting the ends of the units between `said arms. A pin 35 is secured between the arms 31 of each front bracket to give rigidity and to limit the upward movement of the connection 29 therebetween. A split cotter pin 36 is inserted through the arms 31 of each back bracket to retain the arm 28.

Fue-l is supplied to the burner units through a main supply manifold 37 mounted across the back of the box 1 and supported upon bracket arms 38 extending rearwardly from the mounting box frame and held in position by yokes 39. The supply manifold 37 is connected to each burner unit through a suitable valve 41 connected between the manifold and the supply connections or headers 29 in any convenient manner, the supply of fuel to each burner unit being independently controlled by its valve 41. A union 42 connected into the supply connection 29 permits each union' to be readily disconnected from the supply manifold 37 and its connections when desired. A yoke 43 is pivotally connected upon the bracket arms 38 and arranged to be swung downwardly to engage the upper sidesof the supply connections 29 and hold said con-` nections rigidly` against the retaining pins 32 whereby the burner vunits may be held rigidly in position when the burner is being transporte The yoke 43 is arranged to be swung rearwardly as l indicated in dotted lines in Fig. 4 to disengage the connections 29 and permit the ready removal of the units when desired.

The burner units may be constructed with an desired number of burner tubes 26 and in uction tube lsupports 22, and any desired number of units may be installed to obtain burner constructions of a desired size. In the drawings I have illustrated a form Wherein six units are provided, each unit being provided with eight burner tubes and induction tube supports. The units extend horizontally across the box 1, from front to back, and are position as desired. The fire box and furnace body 43 is then constructed over the box in any desired manner. When in service, the fuel supply to any particular burner unit may be shut off and the unit disconnected from the supply manifold connections. A simpley removal of the pins 32 then permits the entire burner unit, with its burner tubes and induction tubes, to be removed from the mounting box for individual repair or replacement without interrupting the operation of the remaining burner units and without requiring that the burner be shut down. This is of particular value and importance as a continuous operating, vertically fired burner, such as required in numerous types of boiler and retort installations, is obtained.

While I have illustrated and described only the preferred construction and arrangement, the details of the structure may of course be modified in numerous ways wit-hout departing from the spirit of my invention. I therefore do not wish to restrict myself to the specific formand construction illustrated and described, but desire to avail myself of all modifications which may fall within the 'comprising a mounting box; aplurality of lburner units; supporting brackets secured within the front and back of the box to receive the ends of the units; detachable retaining` means removably engaging the "comprising a mounting box; a plurality of burner umts; supporting brackets comprising pairs of downwardly extending arms secured `within the front and back of the box,
